Vsevolod Mavrikievich Klechkovsky ((ロシア語:Все́волод Маври́киевич Клечко́вский); also transliterated as Klechkovskii and Klechkowski; November 28, 1900 – May 2, 1972) was a Soviet-era agricultural chemist known for his work with radioisotopes. He graduated in 1929 from the Moscow agricultural academy and worked there from 1930. He became a professor in 1955, and an academician of the All-Union Academy of Agricultural Sciences of the Soviet Union (known as VASKhNIL) in 1956. His use of isotopic labeling in the advance of soil chemistry led to his being considered a founder of agricultural radiology.〔(Newsletter of the International Union of Radioecology ) #43, September 2005, "The XXXIII annual radioecological readings were held in Obninsk, October 21, 2004, and were dedicated to the memory of V.M. Klechkovsky (1900-1972), one of the founders of agricultural radiology."〕〔(Radiation Risk Estimates in Normal and Emergency Situations: Proceedings of the NATO Advanced Research Workshop on Impact of Radiation Risk Estimates in Normal and Emergency Situations, Yerevan, Armenia, September 8-11 2005 ); ed. Arrigno A. Cigna and Marco Durante; Springer〕 He was one of the first to study plant nutrition using radioisotopes, for which he received a Stalin prize in 1952 along with his academy co-workers. He studied the behavior of heavy nuclei daughter isotopes in soils. Following the 1957 Kyshtym disaster, Klechkovsky led the research projects studying the long-term effects of radioactive contamination at the site.〔(Review of ''Nuclear Disaster in the Urals'' by Zhores A. Medvedev ) in the Bulletin of the Atomic Scientists, April 1980〕 Klechkovsky also studied theoretical chemistry, and proposed a theoretical justification of the empirical Madelung rule for the ordering of atomic orbital energies.〔Klechkovsky, V. M. Zh. Exsperim. i Teor. Fiz., 41.465 (1962). (Soviet Physics J. Expt, and Theor. Phys. 14,334 (1962) ) 〕 This rule is therefore sometimes called Klechkovsky's rule, especially in Russian and in French sources. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vsevolod Klechkovsky」の詳細全文を読む スポンサード リンク
